摘要
檩条一般采用简支梁,假定屋面板能阻止其侧向失稳和扭转,则只计算其强度。仅就连续檩条以及隅撑对檩条的附加力导致檩条上翼缘受拉、下翼缘受压,失去屋面板对受压区的侧向支撑时等情况进行分析,希望对工程设计有所裨益。
The purline is often designed as a simple beam, and only it＇s strength needs to be calculated,if the roof panel can prevent it＇s lateral buckling and torsion. It is analysed such aspects ： continuous purline; and the additional force effected by knee brace resulting in the purline＇s top flange in tension and bottom flange in compression, the roof panel can＇t give lasteral strut to compressive zone etc. It is expected that it will be beneficial to the engineering design.
